My present invention relates to improve- -ments in tape coating and affixing devices of the hand manipulated type, and adapted to coat a tape with gum, mucilage, or other simifiller adhesive, and simultaneously affix the coated tape to a desired surface.

While the implement of my invention is adapted for various purposes and uses, it is particularly designed for employment in coating and aflixing printedtelegraphlc records or messages upon the blank sheet, to form the usual telegram. Thus the printed tape or paper strip, after it has received its record, is passed through the implement of i my invention, and during its passage through the implement the liquid adhesive isapplied to .the rear or blank face of the tape', and as the tape emerges from the implement, the tape is affixed to the blank sheet provided therefor. The blank sheet is usually a sheet of paper, and the record tape is affixed to the sheet of paper in parallel lines with the printed side of the paper strip ortape up, and the coated side firmly aflixed to the paper sheet. p In carrying out my invention I prov de a device or hand operated implement equipped with a pressure roller by means of which the coated tape or paper strip is emerges from the implement, and in the affixing of the strip this operation is accomplished without necessity .for handling the coated strip, thus avoiding soiling of the fingers as well as soiling of the paper sheet, and insuring a clean and neatly finished telegram.

The device is simple in construction, com posed of a minimum number of parts compactly associated and readily separated for cleansing, repairs, orv adjustment, and facile I in operation for the performance of its functions.

The invention consists in certain novel combinations and arrangements of parts as Will hereafter be more fully set forth and claimed. In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged rolled and affixed on the sheet as the strip 7 according to the best mode I have thus far devised forthe practical application of the principles of my invention. It will be understood that the parts 'may be fashioned V from suitable materials, invarious sizes and shapes for adapting the implement to a variety of uses. 1 v V Figure 1 is a view in side elevation of the coating and affixing device ofmy invention, showing by dotted lines the paper strip as it is passed through the device and affixed to the surface of a sheet or other object.

Figure 9 is an enlarged detail view of part of the cap of Figure 3. i

In the preferred form ofmy invention I so employ a receptacle '1 of suitable size, and preferably cylindrical in shape, as a reservoir for containing the liquid glue, gum, mucilage, paste or other adhesive to be applied to the tape T. The open end of the receptacle is provided with external threads,

and a cap 2 having a flanged'portion 3 is threaded on the receptacle, to close the open end after the receptacle has been filled to a suitable capacity with the liquid adhesive.

The cap 2 is provided with an elongated, rectangular slot or hole 4 for the outlet of the liquid adhesive, and the lower wall of this slot is fashioned with a serrated knife edge 5 to wipethe paper strip'of excess'coating as the strip passes down in front of the outlet slot. The serrations or teeth in the knife edge tend to form miniature, parallel ridges of adhesive, extending longitudinally of the strip, which ridges are of course displaced or flattenedas the strip or tape is laid" or adhered to the blank or other object to which the tape is to be applied. The coated tape passes the serrated knife edge in frictional contact therewith and excess material is wiped from the tape while at the same time an ample quantity of the adhesive remains on the tape for efficient operation of the device.

Across the outer face of the cap is arranged a transversely extending, integral, tongue 6,

and the slot 4 opens through this tongue. This tongue is the same width as the tape T and the knife edge 5 is flush with the outer face of the tongue. Below the knife edge a groove 7 is formed in the face of the tongue and this groove forms a recess at the coated side of the tape in order thatthe coated side of the tape may pass from the device without contacting with any surface that would otherwise disturb the coating of adhesive. It will of course be understood that the side of the tape toward the interior of the receptacle is coated as it passes the adhesive in the slot at.

On the top of the cap are provided two spaced pins 8 to enter complementary perforations or holes in the bottom of a channel guide 9, in which guide the tape is laid as it comes from the roll, and the tape is guided between the two inwardly converging walls 10 of the channel guide. At its front end, the channel guide is fashioned with a rounded face 11 over which the tape passes smoothly, and by which the'tape is guided to the face of the tongue 6. The channel guide is detachably mounted on the cap by means of the pins and the holes in the guide, and the latter is clamped to the receptacle by means of two pairs of spring arms 12, 12 that clasp or clamp themselves about the receptacle.

At one side of the cap a head 13 is hinged as indicated at 14, and this head is circular in shape and of approximately the same diameter as the cap. The head is adapted to swing to closed position over the face of-the cap, and a spring blade 15, seated in grooves 16 in the sides of the head and cap and secured to the head by a screw, is designed to snap over the edge of thefiange 3 of the cap and fasten the head against the face of the tongued cap. I

Within the head is mounted a pressure plate 17 for the tape T, and this plate, which is the same width asthe tongue 6, is fashioned at its opposite ends with hooks 18. The pressure plate and the face of the tongue 6 form a passage between them through which the tape passes as it is being coated and guided through the device.

A pressure blade 19, of resilient. material,

is fashioned with angular flanges 20 at its ends which flanges bear against the back face of thepressure plate, and an adjustin screw 21 is threaded in the head to provide pressure againstthe blade and plate. The prespressureplate are snapped over these stationary hooks 23, and the pressure plate encloses the pressure blade within this countersunk recess 22'. By turning the screw 21 it will be apparentthat the pressure or tension of the resilient pressure blade against the pressure plate may be varied to vary the space between the pressure plate and the tongue and adjust these guiding elements to the tape passing between them. The side walls of the groove 22 guide the edges of the tape, and the pressure plate holds the tape against the tongue, as well as against the serrated knife edge or scraper 5, to prevent escape of the adhesive and also to prevent application of an excess coating tothe tape. 1

The resilient blade is confined in the countersunk recess of the head by the spaced books 23, 23, and pressure of the screw on the blade 95 holds the flanges of the blade against the pres sure plate with suflicient force to prevent loosening of the parts. For purposes of illustration the parts are exaggerated in Ifigure 5, and the tape is indicated by a dotted lme passing through the groove 22 between the tongue and the pressure plate. It will be understood that the tape, as it passes through the coating device, is held with sufficient friction to prevent buckling of the tape and to prevent leakage of the liquid adhesive, the friction being adjusted or varied by manipulation of the screw 21.

After the tape emerges from the coating device, it is led under a pressure roller 24, indicated in Figure 1, and the coated tape is laid or affixed by the roller on the surface provided for that purpose.

The presser roller isjournaled in the forked arm 25 that is provided with two spaced guide fingers 26, between which fingers the tape is guided to the roller, before it passes under the roller. The forked arm is fashioned integral with an attachingplate 27, which is secured by screws 28 to the outer face of thehead 13, and this attaching plate is provided with a hole 29 to permit ready access of a screw driver or other tool to the adjustin screw 21 of the coating device.

As thus described and illustrated it will be apparent that the device is adapted to uniformly and evenly apply the adhesive to the tape, and the adhesive is prevented from drying before the coated tape is applied to the sheet or other object. 1

The cap and its hinged head may readily be removed from the receptacle for cleaning and filling the receptacle, and the hinged head may readily be turned back or swung to the open position of Figure 3 for threading the tape by hand through the device, as well as for the purpose of gaining access to the operating parts of the device for usual cleaning, adjusting or repairs.

It will be obvious that the coating device may be varied in size to adapt it for the purpose of coating various widths of paper strips or tapes, and while I have illustrated and described the invention as used for coating and aflixing telegraphic records to telegram blanks, it will be understood that the device may be used for sealing the wrappers of 1 packages &c.
